(SOLVED) Under heavy load internet gets killed, only a reboot can bring it back up

Re: (SOLVED) Under heavy load internet gets killed, only a reboot can bring it back up
I 'solved' this by buying a new nic. It's an Eminent with a RTL8139D chipset. you SOLVED it not 'solved'. onboard NICs are usually crap, except high end motherboard. they solder in what's cheapest in the moment. if chips are buggy, they add workaround in windoze drivers. and finally - for average windoze user there is nothing strange that he/she needs to reboot the system many times a day. they don't even know why network stopped working - is it hardware problem, driver problem, system crash. they just reboot. on 3 motherboards i've got with gigabit NIC, 1 are completely unusable (nvidia), one are barely usable after turning off txcsum and rxcsum: re0: RealTek 8168/8168B/8168C/8168CP/8111B/8111C/8111CP PCIe Gigabit Ethernet port 0xd000-0xd0ff mem 0xf900-0xf9000fff irq 17 at device 0.0 on pci4 re0: turning off MSI enable bit. re0: Chip rev. 0x3800 re0: MAC rev. 0x the fully working one is: bge0: Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x4101 mem 0xc010-0xc010 irq 16 at device 0.0 on pci3 miibus0: MII bus on bge0 bge0: Ethernet address: 00:14:5e:94:49:19 bge0: [ITHREAD] but the last one is on IBM server. i've just seen re0: turning off MSI enable bit. looks like fix recently added as i upgraded this machine to 7.1 from 6.3 already funny thing - feature that has to be disabled ;) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Under heavy load internet gets killed, only a reboot can bring it back up
Each time my internet connection is under heavy lead it gets killed after a minute of 10. I tried the following commands to get the internet back up, but nothing helped: /etc/rc.d/netif restart ifconfig mynic down ifconfig mynic up Even worse the last time I issued a '/etc/rc.d/netif restart' my whole system hardlocked (wasn't responding to capslock presses). So far the only solution has been te reboot the computer. Is there any way I can prevent my internet connection from getting killed? How do I get it back up after it has been killed?

FreeBSD 8.0 == CURRENT == HEAD in CVS tag terms. You need to download the data at the below links and save the output in files shown on the left: if_msk.c -- http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/msk/if_msk.c?rev=1.34;content-type=text%2Fplain if_mskreg.h -- http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/msk/if_mskreg.h?rev=1.13;content-type=text%2Fplain These are the msk(4) Ethernet driver in CURRENT. *DO NOT* visit those web pages in a browser then copy/paste the output into a file. Use a tool like fetch(1) or wget(1) to do the work for you. It's not hard. Once you have those two files, you will need to replace your existing driver code with the new files. First make backups: $ cd /usr/src/sys/dev/msk $ cp -p if_msk.c if_msk.c.orig $ cp -p if_mskreg.h if_mskreg.h.orig Now replace the old code with the new: $ cd /wherever/you/downloaded/the/files $ mv if_msk.c /usr/src/sys/dev/msk $ mv if_mskreg.h /usr/src/sys/dev/msk Now you need to rebuild the kernel and install the kernel. In this scenario, when building the kernel DO NOT use any -j flags, as if the driver doesn't build, you'll be scrolling back through pages of data to try and find out why. If the build doesn't occur successfully, paste the errors you get here and one of us can try to figure out why. Otherwise, installkernel and reboot. You should not need to build world for this. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

One thing worth trying would be to disable MSI/MSI-X. You can disable these by adding the following to your /boot/loader.conf : hw.pci.enable_msix=0 hw.pci.enable_msi=0 The command above will disable all MSI/MSIX capability of box. If the intention is to disable MSI feature of Marvell network controller add hw.msk.msi_disable=1 to /boot/loader.conf. But I don't think you need to disable MSI capability unless you have buggy PCI bridges. Without MSI msk(4) would normally share interrupts with other devices(e.g. USB).

I guess the message above could be safely ignored.
Adding Yong-Hyeon PYUN to this thread, since he helps maintain the
msk(4) driver. Yong-Hyeon, do you know of any conditions where heavy
network I/O could cause msk(4) to lock up or stop transmitting traffic,
or possibly hard-lock on ifconfig down/up?
I think workaround for the controller bug was committed to HEAD(SVN
r183346). To original poster, would you try latest if_msk.c from
HEAD?(Just copy if_msk.c/if_mskreg.h from HEAD to your box.)
You got to help me a little bit here. How do I achieve this? Btw I am
running FreeBSD 7.1 BETA. Doesn't that mean the fix is already applied?
It seems that msk(4) in HEAD does not build correctly on RELENG_7.
Try attached patch.
Save attached patch to /path/to/patch
#cd /usr/src/sys/dev/msk
#patch -p0 /path/to/patch/msk.watchdog.diff
And rebuild your kernel.
